IMPR'VEMENT IN STEAM-GENERATORS;

The Shedule referred to in these Letters Patent and making part of diesame I, PETER RILEY, of Lancaster, in. vthe county of Lancaster andStante of Pennsylvania, have invented certain Improvements inSteam-Generators, of which the following is n specification.

Natureand Olyects -of the Iiwjcntz'on.`

Myinrention relntcsto the: manner of combining two water-spaces byhorizont-nl dues or tubes, when such tubes are provided with adjustablevertical dinplirugms, so placed os to expose the greatest `amount otsurface to :m increased or undulztted action 'of the ire, undthcrebysnve fuel.

Description of lwAccmnpunying Drau-'ings'.

Figui-c 1 is n perspective View of the generator, to whiclrmyimprovement is applied, surrounded by brickwork, with the covertoJhcfront witter-space removed. i i Figure. 2 is :t side elevation.

Figure 3, n front elevation of the same.4

General Description.

A'is the wuter-spce over the fire-grate E.

-B is the other water water-space, over the flue K, in the reni'.l

D DStc., the tubes that open into the water-spaces A and B.

G is :t bridge woll, extending. to the rst range of tube D, `n ndcontinued byV n. metallic plate to the third tier .of tlnes.

I and H nre'udiustable dinphrugms, fitting closely A around thc tubesD', but not attached, so that they can be slidv onclc or forward, to ndjust them. I descends centrally from the top downward, und H ascends frombelow the flue K to the third tier of tubes, ns shown.

"Jhe nme or heat is thus carried from the underside.

of the water-space A over the extended bridgewll G, under I, overfH, anddown und beneath the weten space B to the ue K or stzick.4

F is the :ish-pit. v

Gis the sten|n-drnm.

L, a. steam-pipe lending from the water-sluwe B to the stenm-drinn .Y

M is the door-plate. N, u headed serewbolt and nut, for securing it,being made steam :md watertight. This opens directly'to the straight andhorizontal tubes. The rear waterspace, B, may be closed in like manner,thus :tibrding easy access vfor cleaning the. tubes eectnully. 'lhe topof theivuter-spuce A opens directly into thestemu-drnm C. The pipe LCurries off thestemn that may arise in thewa-ter-sl'mce B. Thus, boththe Water und steam has :t free circulation, and the fire n prolongedaction, by the inter-V position of :the adjustable diaphragm, in thema'nner shown, extending ncross from one wall to the other.

a is an iron plate inside, across the water-space A, perforated for thebolts in the door-plateM.

Iam :twnre that two witter-spaces connected by tubes' in un inclined orvertical positionare used; also, that dinpiuwgms, extending `in-uvlongitudinal direc# tion through tnbes,'constrncted 'with flanges at theends; such I do not claim; nor do I broadly cluim t-lfe twowaiter-spaces combined by tubes; but Whnt I do claim us my invention,and desire to se- 'cure by Letters Patent,l is- 'The perforateddiaphmgms H I of a horizontal tubular boiler, when mnde adjustable, asand'for the purpose named.
